Degree to Radian Conversion

Degree : A degree, a degree of arc or arcdegree is a measurement of plane angle, on behalf of 1/360 of a full rotation. The symbol for degree is °. It is not an SI unit, however, it is accepted for use with SI. One degree is equal to π/180 radians.

Radian : The radian is the standard unit of angle which is defined as the ratio between the length of an arc and its radius. It is an SI derived unit, commonly used in many areas of mathematics. One radian is approximately equal to 57.3 degrees. Its symbol is rad, an alternative symbol is the superscript letter c which is infrequently used as it can be easily mistaken for a degree symbol (°).
